blown fuse problem

i have a jenson mp3310 head unit which is 45x4.......a menace 200 watt amp.......and a polk audio 10 inch sub with a wedge box.  everytime i turn the bass up too high......one of my fuses in the fuse box keeps blowing.....the fuse that blows is the interier lights fuse.

i wired everything to the head units' power, ground, and remote wires.  i even turned down the bass on the amp itself........it is only turned up like 10 percent and when i put the bass up on my head unit........or if i turn the volume up too high.......the fuse blows!!! 

does anyone kno how to fix this problem?  thanks and please help.....

lemme get this straight.......i will need to have an 8 guage wire from the battery itself to the amp and a ground of its own?  i cant use the head units' power and ground? 

so this will stop my interier lights fuse from blowing riote?  and i will be able to use my amp at full power?  i will get on this project today and let u guys kno if it wrks......thanks.

by the way.......wut do u mean by "fuse your power lead 10 inches from the battery with the same value fuse thats on the amp".  my amp has a 20amp fuse on it.

yes you will need a wire on its own going to the amp,and keep the ground wire as short as possible making sure to clean any paint off the surface before screwing down so it has a less resistive connection to the body of the car.

2-no you can not use a head units power and ground!

3- yes This should stop the fuse from blowing for your lights!

4- the power wire of an amp must be fused to protect the wire from starting a fire if ever shorted on metal or something.(Note that the fuse on the amp only protects the amp not the wire so this is why we need to put fuses near the battery in the event of a short circuit.)

ok guys.......i went to the store got some 8 guage wire but i was confused bout the amp.

i saw two types of fuse holders for 8 guage wires..........cylindrical.......or blade type.  they can both handle up to 30 amps.  i asked the worker ther and he sed ther basically the same but the cylindrical one is more for looks.  i bought the blade type cuz it was only 6 bucks while the cylindrical one was around 20.  does it really matter if its blade or cylindrical?

thanks guys........and how do i connect the 8 guage to the battery?  i didnt buy any special connectors.....do i need one?  or can i just jam it in ther?

thanks for all the help..........im a noobie to this......always lernin

WELL YOU SHOULD HAVE NO PROBLEM THIS IS WHAT YOU DO AND THIS IS EASY ONCE YOU DO IT YOU WILL ALWAYS KNOW HOW TO DO IT.

USING A CONNECTOR CONECT ONE SIDE OF BLADE FUSE TO BATTERY POWER WIRE, THE RED ONE. CONNECT THE 8 GUAGE WIRE TO THE SECOND SIDE OF THE BLADE FUSE, PUT AT LEAST A 30 AMP FUSE IN THE FUSE HOLDER. RUN THE 8 GUAGE WIRE THROUGH THE FIRE WALL(METAL PLATE ABOVE PEDALS) FIND A RUBBER COVER OR SOME TYPE OF HOLE THAT GOES ALL THE WAY THROUGH FROM THE ENGINE TO THE GAS BRAKE PEDAL RUN THAT WIRE UNDER DASH OR UNDERNEATH SIDE MOLDINGS TO REACH THE BACK IF YOU AMP IS IN THE BACK I AM SURE YOU HAVE DONE THIS WITH THE RCA CABLES. DISCONNECT THE POWER AND GROUND WIRE YOU CONNECTED IN THE FIRST PLACE. LEAVE THE REMOTE WIRE THIS AS YOU KNOW , YOU WILL NEED. CONNECT THE POWER WIRE (8GUAGE WIRE FROM BATT) TO THE POSSITIVE TERMINAL OF AMP. IF YOU HAVE LEFT OVER 8 GUAGE WIRE FROM POWER WIRE USE THAT FOR GROUND I KNOW THAT MAY BE RED BUT THATS OK IT WIRE. CONNECT IT TO GROUND TERMINAL ON AMP. AND USE A TAPPING SCREW TO SCREW INTO A METAL SURFACE ON THE OTHER SIDE OF GROUND WIRE . AFTER THAT PLACE FUSE IN FUSE HOLDER CONNECTING TO BATT AND TURN THE CAR ON TEST OUT ANY PROBLEM EMAIL OR POST.. PS MAKE SURE WHEN RUNNING THE POWER WIRE BY STEERING WHEEL NOT TO PUT IT UNDER PEDALS OR BY STEERING WHEEL BECAUSE YOU DONT WANT WIRE GETTING CAUGHT AND BRAKING ON SOMETHING. I AM SURE YOU NOT DUMB SO DONT DO IT.
